Answer:

If we're just comparing them, I'm assuming that the answer is that they're the same because of PEMDAS.

Answer:

X = 50; Y = 50

Answers are the same by following the correct order of operations.

Step-by-step explanation:

This problem deals with the correct order of operations. Multiplication is done before addition.

22 * 2 + 6 = X

44 + 6 = X

X = 50

6 + 22 * 2 = Y

6 + 44 = Y

Y = 50

The answers are the same despite the order in which the operations were written since by following the correct order of operations, you must do the multiplication first in each chase.

14.88 + x = 17.05 What is the value of x?

Masteriza [31]

Answer:

x=2.17

Step-by-step explanation:

14.88+x=17.05

We move all terms to the left:

14.88+x-(17.05)=0

We add all the numbers together, and all the variables

x-2.17=0

We move all terms containing x to the left, all other terms to the right

x=2.17

What is 1 plus -1/8????????

Kazeer [188]

7/8, 1 is also 8/8 so if you add that to -1/8 (then it automatically subtracts since it’s adding a negative) making 7/8.

If x^6=60 and w^10=20, what is x^12×w^-10? A. 36, B. 60, C. 180 or D. 360

tigry1 [53]

Answer:

$x^{12} w^{-10}$

And we can find this rewriting the expression in terms of the info given and we got:

$x^{12} w^{-10} = (x^6)^2 (w^{10})^{-1}$

And replacing we got:

$x^{12} w^{-10} = (60)^2 (20)^{-1}= \frac{60^2}{20}= 180$

And the best option would be:

C. 180

Step-by-step explanation:

For this case we know that:

$x^6, w^{10} = 20$

And we want to find the value for:

$x^{12} w^{-10}$

And we can find this rewriting the expression in terms of the info given and we got:

$x^{12} w^{-10} = (x^6)^2 (w^{10})^{-1}$

And replacing we got:

$x^{12} w^{-10} = (60)^2 (20)^{-1}= \frac{60^2}{20}= 180$

And the best option would be:

C. 180

Hannah has some pennies and some nickels. She has a maximum of 25 coins worth a minimum of $0.65 combined. If Hannah has 11 nick

kotykmax [81]

Answer:

Minimum number of pennies = 10

Step-by-step explanation:

Given:

Maximum number of coins Hannah have = 25

Total number of of nickels (coins) she has = 11

Total value of the combined coins = $ 0.65

We have to find the minimum number of pennies.

Let the number of pennies be "p" and no. of nickels be "n".

Note:

Value of 1 penny = $ 0.01

Value of 1 nickel = $ 0.05

Arranging the above situation in terms of equations:

According to their quantities.

⇒ $n+p\leq 25$ and $11+p\leq 25$ so $p\leq 14$

According to their values.

⇒ $0.05(n)+0.01(p)\leq \$\ 0.65$

⇒ $0.05(11)+0.01(p)\leq \$\ 0.65$

⇒ $\$\ 0.55+0.01(p)\leq \$\ 0.65$

⇒ $0.01(p)\leq \$\ 0.65-\$\ 0.55$

⇒ $0.01(p)\leq \$\ 0.10$

⇒ $(p)\leq\frac{ \$\ 0.10}{0.01}$

⇒ $(p)\leq 10$

Minimum number of pennies :

⇒ $(p)\leq 10$ which also satisfies $p\leq 14$

Therefore :

⇒ $p=10$

Plugging p= 10 we can verify the values.

⇒ $0.05(11)+0.01(10)\leq \$\ 0.65$

⇒ $0.55+0.10\leq \$\ 0.65$

⇒ $\$\ 0.65\leq \$\ 0.65$

So,

Minimum number of pennies Hannah have = 10
